Do you have any Source of your claim that there was no contingency plan?
FAA regulations seems to indicate that there are plans:
"(5) Procedural means.
g. Procedural Mitigations. If one or more onboard EFBs fail, resulting in loss of function
or the presentation of false or hazardously misleading information, a contingency plan or process
will need to be in place to provide the required information."
The same articles says:
"The pilot told us when they were getting ready to take off, the iPad screens went blank, both for the captain and copilot, so they didn’t have the flight plan,” " (emphasis mine)
What I meant is taht they didn't have a second electronic contingency plan. Probably they had to switch to paper on those flights (otherwise the impact would have been minimal)
